Lyrics:

I'm not that lonely anymore
I hardly ever walk the floor
I don't cry every night like I used to
No, I don't wear your stupid ring
I wouldn't hang on to the thing
It's the last thing I have to hold on to
And if you believe that you believe anything
So while I've got your undivided attention
I think I discovered the truth
One of us is the world's biggest fool
I took your pictures off the wall
There's nothing left 'round here at all
To remind me of when we were together
Yeah, life is perfect everyday
There ain't a thing that I would change
And I hope that it stays like this forever
And if you believe that you believe anything
So while I've got your undivided attention
I think I discovered the truth
One of us is the world's biggest fool
Yeah, I blame you and you blame me
That's what they said in therapy
Now we say that we're through with one another
I hope the dog is doing fine
No, I still haven't changed my mind
And you know I love livin' with my mother
And if you believe that you believe anything
So while I've got your undivided attention
I think I discovered the truth
One of us is the world's biggest fool
Oh, yeah, I think I discovered the truth
One of us is the world's biggest fool
